How to store and retrieve JSON data into local storage?

Question

I have this code:

var string = \'{\"items\":[{\"Desc\":\"Item1\"},{\"Desc\":\"Item2\"}]}\';
localStorage.setItem(\'added-items\', JSON.stringify(string));
         


        

Answer 1

var object = Json.parse(retrievedObject);

Now you can access it just like an array

If you need more help i have some previous code where i am reading Json from local storage and making a form from that json. This code will help in understanding how to traverse that array

Json stored in localstorage

{"form":[{"element":"input", "type":"text","name":"name","value":"value","min":"2","max":"10"}]}

JavaScript to read that json

function readJson(){
    if(!form_created){
        add_form();
    }
    var fetched_json = localStorage.getItem("json");
    var obj=JSON.parse(fetched_json);
    for(var i=0; i
